  • the present disclosure relates to an imaging control apparatus and a method for controlling the image control apparatus, and particularly to a technique for setting a position where specific processing relating to image capturing is performed.
  • Japanese Patent Application Laid-Open No. 2012-203143 discusses a technique in which a user moves an AF target frame by performing a touch operation on a touch panel while looking into an in-finder display unit, and determining the display position of the AF target frame as an AF position through a double-tap.
  • AF processing automatic exposure (AE) processing, white balance (WB) processing, and the like are performed in both still image capturing and moving image capturing.
  • the AF processing is performed as follows.
  • still image capturing the user specifies the AF position before capturing an image.
  • moving image capturing the user can specify an AF position before starting recording a moving image, and can change the AF position in the middle of moving image recording. If the method discussed in Japanese Patent Application Laid-Open No. 2012-203143 is applied to still image capturing, the user needs to perform a double-tap operation, after moving the AF target frame, to specify the AF position. Therefore, the user may possibly miss image capturing opportunities. To solve such a problem, the user can move the AF position to the frame position according to the movement of the AF target frame. In this case, however, an image automatically focused at a position other than a desired position may be recorded at the time of moving image recording.
